So Cisco's AnyConnect prevents access to virtual local networks, too, great!

Turns out, you can do more with a serial port in VMware Fusion than logging it's output. Like, use it as a proper serial console so you can log in when something is messing with your network stack.

This primarily shows @kuenishi's directions still work on macOS 10.14 Mojave with VMware Fusion 11.x Pro.

1. Create VM, add serial port, make sure VM is shut down, edit .vmx file's `serial0' lines to look like this:

if [ ! -z "$1" ] && [ "$1" = "-u" ]; 
then
    UPDATE_SRC=true
    if which svn; then
        SVN=`which svn`
    elif which svnlite; then
        SVN=`which svnlite`

I added a 256GB mSATA SSD to my Lenovo x220 of which I planned to use a nice chunk as L2ARC for the SATA HDD. Even without a SATA disk present the SSD showed up as HDD2 in the BIOS.
